Digital signs are a form of electronic display that shows television programming, menus, information, advertising and other messages. Digital signs (frequently utilizing technologies such as LCD, LED, plasma displays, or projected images to display content) can be found in both public and private environments, including retail stores, hotels, restaurants, and corporate buildings, amongst other locations.

Digital sign displays are most commonly controlled by personal computers or servers, through the use of either proprietary software or free software; this approach often allows the operator to avoid large capital outlays for the controller equipment.
Advertising using a digital sign is a form of out-of-home advertising in which video content, advertisements, and/or messages may be displayed on digital signs with a common goal of delivering targeted messages, to specific locations and/or consumers, at specific times. This is often called “digital out of home” or abbreviated as DOOH.
Since digital sign content may be both frequently and easily updated, saving the printing and/or construction costs associated with a static sign, and also because of the interactive abilities available through the accompanying employment of such real-world interfaces as embedded touch screens, movement detection and image capture devices, it has won wide acceptance in the marketplace.
